Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated substations, specifically relating to a moisture-proof prefabricated substation based on circulating ventilation. Background Technology

[0002] Prefabricated substations, also known as prefabricated transformer substations, are factory-prefabricated, compact indoor and outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. They organically combine transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. Particularly suitable for urban power grid construction and renovation, they represent a new type of substation that has emerged after traditional civil engineering substations. Box-type substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering distribution rooms and substations, becoming a new type of complete power distribution system.

[0003] Existing prefabricated substations use louvered openings for natural ventilation. However, due to the large amount of equipment installed inside, natural ventilation creates dead zones, leading to localized moisture accumulation and failing to meet the moisture-proof ventilation requirements of prefabricated substations. Therefore, we propose a moisture-proof prefabricated substation based on circulating ventilation. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-proof prefabricated substation based on circulating ventilation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof prefabricated substation based on circulating ventilation, comprising:

[0006] The prefabricated substation body has a canopy on its top.

[0007] A top air intake turbulence assembly is provided, and the top air intake turbulence assembly is symmetrically arranged at an inclined angle on the top of the prefabricated substation body;

[0008] The side air intake ventilation assembly is provided in four parts, and the four side air intake ventilation assemblies are symmetrically arranged at the side door of the prefabricated substation body.

[0009] Bottom circulation exhaust assembly, which is located at the bottom of the prefabricated substation body.

[0010] Preferably, the partition is mounted on top of the prefabricated substation body via a support plate.

[0011] Preferably, a 10-15cm air intake space is reserved between the partition and the top of the prefabricated substation body.

[0012] Preferably, the top of both the partition and the prefabricated substation body has a triangular structure that slopes downwards from the middle to both sides.

[0013] Preferably, the top air intake spoiler assembly includes a centrifugal fan and a spoiler impeller;

[0014] The centrifugal fan is installed at the top of the prefabricated substation body at an inclined angle, the turbulence fan wheel is installed at the bottom of the centrifugal fan, and the turbulence fan wheel is connected to the output shaft of the centrifugal fan.

[0015] Preferably, the turbulence fan wheel is a five-bladed fan wheel.

[0016] Preferably, the side air intake ventilation assembly includes an air intake grille, an air intake chamber shell, and an axial flow fan;

[0017] There are two air intake grilles, which are symmetrically arranged on the upper and lower parts of the side door of the prefabricated substation body. The air intake chamber shell is located on the inner side of the side door of the prefabricated substation body at the position corresponding to the two air intake grilles. The axial flow fan is located at the center of the air intake chamber shell.

[0018] Preferably, the bottom circulating exhaust assembly includes an exhaust grille, a guide plate, and a DC fan;

[0019] The exhaust grille is located at the bottom of the prefabricated substation body. Several guide plates are provided, and the guide plates are symmetrically and obliquely arranged at the bottom of the prefabricated substation body below the exhaust grille. The DC fan is located on the side of the bottom of the prefabricated substation body corresponding to the guide plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model is equipped with a top air intake turbulence component, which adopts a centrifugal fan and a turbulence fan wheel set according to the tilt angle of the top of the prefabricated substation body. When in use, the centrifugal fan introduces external air into the prefabricated substation body and drives the turbulence fan wheel to rotate, disturbing the airflow entering the prefabricated substation body. Since the centrifugal fan is symmetrically tilted, the airflow entering the prefabricated substation body is also tilted. Through the disturbance of the turbulence fan wheel, the airflow is disturbed and circulated to all parts of the prefabricated substation body, eliminating dead airflow corners, avoiding local moisture accumulation in the prefabricated substation body, and improving the moisture-proof performance of the prefabricated substation body.

[0022] 2. This utility model is equipped with symmetrically distributed side air intake ventilation components. In use, external air is drawn into the air intake chamber shell through the air intake grille by the axial flow fan, and then blown into the prefabricated substation body by the axial flow fan. Since the axial flow fans are symmetrically distributed, the airflow of the axial flow fans will form convection, further disturbing the airflow, making the airflow more complete, further eliminating airflow dead zones, and improving the moisture-proof performance of the prefabricated substation body.

[0023] 3. This utility model is equipped with a bottom circulation exhaust assembly. In use, the air inside the prefabricated substation body is drawn into the bottom cavity of the prefabricated substation body through the exhaust grille plate by the DC fan, and then guided by the guide plate and discharged by the DC fan. This effectively removes the humid air inside the prefabricated substation body. At the same time, the inclined guide plate can effectively prevent external bottom moisture from entering the prefabricated substation body, further improving the moisture-proof performance of the prefabricated substation body.

[0024] 4. This utility model is based on the double-layer roof structure formed by the partition and the top of the prefabricated substation body, so that a rainproof and dustproof space is formed between the partition and the top of the prefabricated substation body, preventing water vapor from entering the prefabricated substation body through the top air intake turbulence component, ensuring a dry environment inside the prefabricated substation body, and improving the protective performance of the prefabricated substation body.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-8 The present invention provides a moisture-proof prefabricated substation based on circulating ventilation, comprising:

[0036] The prefabricated substation body 1 has a canopy 2 on its top. The canopy 2 is set on the top of the prefabricated substation body 1 through a support plate 6. An air intake space of 10-15cm is reserved between the canopy 2 and the top of the prefabricated substation body 1. Both the canopy 2 and the top of the prefabricated substation body 1 have a triangular structure that slopes downward from the middle to both sides.

[0037] This utility model is based on the double-layer roof structure formed by the partition 2 and the top of the prefabricated substation body 1, so that a rainproof and dustproof space is formed between the partition 2 and the top of the prefabricated substation body 1, preventing water vapor from entering the prefabricated substation body 1 through the top air intake turbulence component 3, ensuring a dry environment inside the prefabricated substation body 1, and improving the protective performance of the prefabricated substation body 1.

[0038] The top air intake turbulence assembly 3 is provided in several units. The several top air intake turbulence assemblies 3 are symmetrically arranged at an inclined angle on the top of the prefabricated substation body 1. The top air intake turbulence assembly 3 includes a centrifugal fan 301 and a turbulence fan wheel 302. The centrifugal fan 301 is arranged at the top of the prefabricated substation body 1 according to the inclined angle of the top of the prefabricated substation body 1. The turbulence fan wheel 302 is arranged at the bottom of the centrifugal fan 301 and is connected to the output shaft of the centrifugal fan 301. The turbulence fan wheel 302 is a five-bladed fan wheel.

[0039] This utility model is equipped with a top air intake turbulence assembly 3, which uses a centrifugal fan 301 and a turbulence fan wheel 302 arranged according to the top tilt angle of the prefabricated substation body 1. In use, the centrifugal fan 301 introduces external air into the prefabricated substation body 1 and drives the turbulence fan wheel 302 to rotate, disturbing the airflow entering the prefabricated substation body 1. Since the centrifugal fan 301 is symmetrically tilted, the airflow entering the prefabricated substation body 1 is also tilted. Through the disturbance of the turbulence fan wheel 302, the airflow is disturbed and circulated to all parts of the prefabricated substation body 1, eliminating dead airflow corners, avoiding local moisture accumulation in the prefabricated substation body 1, and improving the moisture-proof performance of the prefabricated substation body 1.

[0040] There are four side air intake ventilation components 4, which are symmetrically arranged at the side door of the prefabricated substation body 1. Each side air intake ventilation component 4 includes an air intake grille 401, an air intake chamber shell 402, and an axial flow fan 403. There are two air intake grilles 401, which are symmetrically arranged at the upper and lower parts of the side door of the prefabricated substation body 1. The air intake chamber shell 402 is located on the inner side of the side door of the prefabricated substation body 1 at the position corresponding to the two air intake grilles 401. The axial flow fan 403 is located at the center of the air intake chamber shell 402.

[0041] This utility model is equipped with symmetrically distributed side air intake ventilation components 4. In use, external air is drawn into the air intake chamber shell 402 through the air intake grille 401 by the axial flow fan 403, and then blown into the prefabricated substation body 1 by the axial flow fan 403. Since the axial flow fans 403 are symmetrically distributed, the airflow of the axial flow fans 403 will form convection, further disturbing the airflow, making the airflow more complete, further eliminating airflow dead zones, and improving the moisture-proof performance of the prefabricated substation body 1.

[0042] Bottom circulation exhaust assembly 5 is located at the bottom of the prefabricated substation body 1. Bottom circulation exhaust assembly 5 includes an exhaust grille 501, a guide plate 502, and a DC fan 503. The exhaust grille 501 is located at the bottom of the interior of the prefabricated substation body 1. Several guide plates 502 are provided, and several guide plates 502 are obliquely and symmetrically arranged at the bottom of the prefabricated substation body 1 below the exhaust grille 501. The DC fan 503 is located on the side of the bottom of the prefabricated substation body 1 corresponding to the guide plate 502.

[0043] This utility model is equipped with a bottom circulation exhaust assembly 5. In use, the air inside the prefabricated substation body 1 is drawn into the bottom cavity of the prefabricated substation body 1 through the exhaust grille 501 by the DC fan 503, and then guided by the guide plate 502 before being discharged by the DC fan 503. This effectively removes the humid air inside the prefabricated substation body 1. At the same time, the inclined guide plate 502 can effectively prevent external bottom moisture from entering the prefabricated substation body 1, further improving the moisture-proof performance of the prefabricated substation body 1.

[0044] In summary, the method of using the moisture-proof prefabricated substation based on circulating ventilation provided in this embodiment is as follows: During use, the centrifugal fan 301 introduces external air into the prefabricated substation body 1 and drives the turbulence fan wheel 302 to rotate, disturbing the airflow entering the prefabricated substation body 1. Due to the symmetrical and inclined distribution of the centrifugal fan 301, the airflow entering the prefabricated substation body 1 is also inclined, and is disturbed by the turbulence fan wheel 302, causing the airflow disturbance to circulate to all parts of the prefabricated substation body 1. The axial flow fan 403 draws external air into the air intake chamber shell 402 through the air intake grille 401, and then blows it into the prefabricated substation body 1. Inside the substation body 1, due to the symmetrical distribution of axial flow fans 403, the airflow of the axial flow fans 403 will form convection, disturbing the airflow and making the airflow more complete, eliminating dead air zones. The DC fan 503 draws the air inside the prefabricated substation body 1 into the bottom cavity of the prefabricated substation body 1 through the air outlet grille 501, and guides the airflow through the guide plate 502 before discharging it through the DC fan 503. This effectively removes the humid air inside the prefabricated substation body 1. At the same time, the inclined guide plate 502 can effectively prevent external bottom moisture from entering the prefabricated substation body 1, improving the moisture-proof performance of the prefabricated substation body 1.
